/** Changelog:
 * 2025-01-12 tonhuisman: Add support for MQTT AutoDiscovery
 * 2024-04-27 tonhuisman: Read sensor asynchronously to enable (the new default) trigger on changed value
 * 2024-04-26 tonhuisman: Migrate 'Send event when value unchanged' and 'Trigger delta' settings from P113 (at last...)
 *                        Add Direction value, -1 = closer, 0 = unchanged, 1 = further away
 * 2022-06-22 tonhuisman: Remove delay() call from begin(), handle delay via PLUGIN_FIFTY_PER_SECOND
 *                        Reformat source (uncrustify)
 * 2021-04-05 tonhuisman: Removed check for VL53L1X as that is not compatible with this driver (Got its own plugin P113)
 * 2021-02-06 tonhuisman: Refactored to use PluginStruct to enable multiple-instance use with an I2C Multiplexer
 * 2021-01-07 tonhuisman: Moved from PluginPlayground (P133) to main repo (P110), fixed some issues
